Disclaimer: I helped found this initiative and I’m hardly neutral on it. I’ll do my best to stick to the facts here but first, I’ll say this: It’s been awesome.

Passports with Purpose, the travelbloggers fundraiser, turns four this year. Founded in 2009 by four Seattle based bloggers, the initiative pulls together bloggers and travel providers (and their PR reps) to raise money for carefully vetted nonprofit causes that focus on education as a channel to alleviate poverty and improve quality of life. Oh, and there are fabulous prizes, too — for example, last year, Gadling’s Mike Barish gave away a SkyMall gift card.

This year, Passports with Purpose (PwP) is supporting Room to Read, the literacy program founded by John Wood after he’d trekked through Nepal. PwP aims to raise enough money to fund the contstruction, staffing, and provisioning of two libraries in Zambia.

In 2010, PwP raised more than $60,000 for Land for Tiller’s Freedom (LAFTI). The funds were used for construction of 25 homes for families in Southern India. PwP co-founder Beth Whitman attended the ground breaking ceremony for the village in Karrungani, Tamil Nadu. On the conclusion of last year’s fundraiser, PwP recieved this note from Peggy Burns, Exective Director of Friends of LAFTI:

We are so excited that 25 families in Karunganni will soon have a decent place to live. It is all thanks to you, your generous sponsors, and over 300 caring individuals who wanted to make this world a better place. Bravo to all of you.

In 2009, PwP raised nearly double the original goal of $13,000 and funded the construction of a school in rural Preah Vihear, Cambodia. The overage was allotted to additional services that ensure the continued success of the project. Michelle Duffy attended a ribbon cutting ceremony at the Passports School in March, 2011.
